While that may turn out the be the case, I wouldn't jump to the conclusion that the fork is a replacement based on the unused cantilever bosses. The seat stays have unused cantilever bosses too and contrasting forks were a popular style around this time. The bicycle has obviously been extensively rebuilt.
